Filed: 1985-06-12
Abstract: PURPOSE:To control the quantity of a laser beam without disordering the position of a diffracted laser beam by providing a means which varies the total level of an acoustic signal applied to an acoustooptic element according to external operation. CONSTITUTION:An acoustic signal 12 outputted by the driving circuit 3 of an acoustooptic modulator is supplied to a transducer 2 to drive the acoustooptic element 1.
